To all whom it may concern Be. it known that I, ALBERT HENRY SMITH,

, a-subject of the King of Great Britain, and

a resident of Birmingham, in the county of Warwick, England, haveinvented certain;- new and useful Improvements in N1pples--- for'BowdenWire Mechanism and the like and I do hereby declare that the followingis same - My invention. comprises improvements "innipples for Bowdenwire mechanism, and.

refers to that class of such which are designed to provide-a mechanicalconnection with the end of thelength of stranded wire,

the object of the present invention being toprovide an improved andsimple. arrange ment of the kind whereby a connection is i establishedwithout the use of solder 'or thelikep I I It has been proposed to forma rope socket,

especially for wire rope, having its main.

body ofsleeve-like form and provided with a tapered plug member, whichfits withinthe' V 'end of .thewireafter the wire has. been in-jserted'in the sleeve',ilin combination with a nut or screwedpart,:whichforces. the ta jpered plug-into the-end of the .Wire, thuseffecting a mechanical'connection between wire and sleeve, by grippingthestrands' between the tapered face of the plug and the interior of thesleeve.

According tomy invention, the plug cooperates with a preferably taperedshoulder between portions of smaller and l'argerdi ameter within thesleeve so that the; strands' p'of-the wire which-enter thesleeveapproxi-E mately parallel toone'another, are bent out .7 dlywithin. the; should eryandiagaingtofi come more or less parallelwithin-the; por-f .tion having a larger diameter, thisdoublei bend inthestrandscombined with the .grip' pin action both-atand above theshoulder ma es the connection extremely secure Referring to thedrawingszeFigure 1.-is

Fig. L-isTl Incarrying my invention into practice as illustrated upon the accompanyingdrawings intothe end of the stranded wire the stranda full, clear, andexact description of the ed wire is gripped between the exterior of"shape, so that the cap and sleeve may be ,tightly screwed together, theinterior of the cap being so arranged as to provide the nee-- into theend of the stranded wire. Thejunction' or shoulder a"? between the twobores Within the sleeve is preferably tapered or conical, -theone'extremity of the plug being ofsimilar form.

As shown in Figs. 14 the plug is provided with a shoulder c and reducedextremity 0 whereby it is riveted to the cap so that the cap and plugmove together all being so arranged that when the-stranded wire isinserted into the sleeve and the cap screwed on, the plug is forced intothe end of the wire, firmly gripping it against the interior thesleeve.- Or as shownby Figs. 5- -8 the "i plug' may be loose within thecap: being a merely adaptedto-be pressed into the end of. the stranded:wi'ra u' Y 11.
